You know all those DVD "special features" where they show raw film footage and then the same scene as edited/processed for the movie? And the movie scene always looks darker (sort of more blue-ish/brown-ish, I guess) than the raw footage? Is that the standard movie "look" that is done in post processing? What is this post-processing called? Can anyone set me straight about this?
What lethal and dkngoth3cpo said.
Über Simplifiedly:
In general the movie is shot to film (still..).
When shooting,generally the primary concern is to get as much information to the film (negative) as possible. So that you have
some details in the shadows and
some details in the highlights. That way you have as much material to work on in the post processing. Some cinematographers use more heavily filters (on camera and lights) to pre set the tone, ia. light coming from window being blue and inside is very warm.Some go even further like Darius Khondji in Seven where he used preflashed negative for shooting: They flashed the film before shooting (or during the shoot with a extra in lens light) with a green/brown light make a "base hue" to the film,to help them achieve the look in the post.
After shooting the negative is carefully developed.
From those negatives,direct positives are made (looks like classic slide film) for direct projecting and dailes are made and put to video and sent to director&cinematographer for the next days previews,to check out that everything is on track.
Theese are what you might have seen.
Or.
Materiel gotten out from video assists.
Video assist is a videocamera that is installed on the moviecamera.It is designed to provide the operator+director a view that the camera sees,shot from the groundglass of the moviecamera.Videoassist provides the picture to the small screen you see on the top of the moviecameras.That picture is not either "color correcte" but a very raw version.
After
that certain cinematographers might make a extra negative of the original for example do bleach by pass,wich in short is abusing+under/over developing+coloring to it or other unorthodox things.
Or some other manipulation of the negative.
After the DPs (director of photography/cinematographer) thing they have base built,they send the film to grading,in wich they set a certain tone to the film in the laboratory.
Nowadays,after they have the raw edit (or final edit) that they scan in the film and send it for the final grading with computers.
They use systems like davinci,or even maybe FCPs Color to do it.
There the film is graded/color corrected on a shot by shot basis, they adjust the colors,blacks,highlights under the supervision of the DP (some cases the director) to make sure the film achieves it´s final look.
After all the circus they make a final negative of the film.That negative (and its copies) are used to make the projection reels of the films.The reels that we see in our theaters.
Obviously it is a lot more complicated but that is "approximately" how it happens...
